Introduction


17/25

Several Definitions

Wayne Wolf Any device that includes a programmable

computer but is not itself intended to be a

general purpose computer.Jonathan W. Valvano

An Embedded computer system includes a

microcomputer with mechanical ,chemical andelectrical devices attached to it, programmed

for a specific dedicated purpose ands packaged

as a complete system.


18/25

RajKamal

An embedded system is a one that has computer

hardware with software embedded in it as one

of its most important component.

In a nutshell: Embedded Systems Computers

Embedded systems overview

Computing systems are everywhere

Most of us think of desktop computers

PCs

Laptops

Mainframes

Servers

But theres another type of computing system

Far more common...
